#CryptoFees101 Crypto fees are the commissions charged for transactions on the blockchain. They depend on the network, congestion, and the type of operation. In Ethereum, these fees are called gas fees — they cover computational costs and depend on the complexity of the action. In Bitcoin, the fee goes to miners for including the transaction in a block. In fast networks like Solana, Polygon, or Tron, the fees are minimal — often less than a cent. There are also exchange fees when trading and bridge fees when transferring assets between networks. Fees ensure security, incentivize validators, and allow for speed regulation. During high demand, they can sharply increase, especially in popular networks.
